Abstract: Abstract Effects of extra strain and dilatation rates on the turbulence structure in nozzles with fully developed supersonic pipe flow as inflow condition are investigated by means of DNS and LES using high-order numerical schemes. It is found that weak favorable pressure gradients already strongly inhibit the Reynolds stresses via corresponding changes of production and pressure-strain terms. The results constitute a database for the improvement of turbulence models for compressible flows.
